The hospitality industry is complex, covering a wide range of jobs, locations, activities, and economic brackets. It includes four main sectors: food and beverage, lodging, recreation, and travel/tourism. The hospitality field aims to create shareholder wealth by satisfying guests through services. A key aspect is that the service provider is often part of the product itself, so guests want to feel valued by workers providing the service. The industry involves both tangible products like food/rooms and important intangible qualities of staff and service delivery.
